Question: what is your favourite planet and why because mine is mars for one reason that is water traces were found on mars so there could be life on mars.

hi totallygnarlly thanks for the excellent question!
Yes i would agree with you – mars is my favourite for the same reason! currently i think astrobiologist believe there probably was microbial life on mars millions of years ago, and that some may still exist now. Recently there have been detected some weird clouds of methane gas detected in the mars atmosphere, and this could be the breath of microbes in the rock!
